doesnt the thc degrade after a certain point? if im playing it safe i harvest at 10% for indica, 30% for sativa, 10-30% for hybrids.I don't go by the trichomes, I wait till all the white hairs have receeded back into the buds, and I mean almost every one...I don't overgrow them but I do like a couchlock stone... Usually takes anywhere from 8-12 weeks depending on the strain....That's why I don't like full sativas, they take too long...lol...
